Measurement & display

Analog input

A read-only measured value: a temperature, humidity, CO₂ level, wind speed — anything with a number and a unit.

At a glance: name, the live reading with its unit. There are no controls.

Trending sub-type. If your installer enabled trending on the measurement, tapping it opens a trend page:

  1. The current reading with its direction (rising or falling).
  2. The curve over the selected window.
  3. A period stepper (‹ ›) pages back and forth through past days, weeks, months, or years.
  4. MIN · AVERAGE · MAX for the window on screen.
  5. The period picker: Hour / Day / Week / Month / Year.

📘 Note: The trend page needs history logging on that measurement, enabled by your installer. Non-trending inputs simply display their value.

Phone, an Analog input row — Phone layout.
Phone, an Analog input row — Tablet layout.
Phone, an Analog input row — Wall panel layout.

Analog output

A value you set rather than read: a target humidity, a pump speed, a valve position.

At a glance: name, the current value, and a setpoint slider that works directly on the row or tile — drag it and the new value is sent. No detail page.

Text display

A text value written by the system — for example a status message from an integration, an automation or the Logic engine ("All systems OK"). The text is read-only in the app.

At a glance: name and the current text. Tap the field, type the new text, and confirm to send it. No detail page.

Webview

A row that opens one of your home's dashboards — charts and gauges prepared by your installer on the built-in Grafana service or any html webpage.

At a glance: name and icon. Tap the row to open the dashboard full screen; tap back to leave it.

Frequently Asked Questions

Why can’t I change an analog input reading?

An analog input is a read-only measurement. An analog output is the widget type used to send a numeric target value.

What is required for a measurement trend chart?

The measurement needs the Trending sub-type and history logging enabled by your installer.

How do I inspect older measurements?

Open the trend page, choose Hour, Day, Week, Month or Year, then use the period stepper. The page shows minimum, average and maximum for the displayed window.

How do I open an installer dashboard?

Tap its dashboard row to open it full screen, then use Back to leave.
